About the upgrades

The State Government is committed to improving road safety across regional South Australia. Important regional highways and roads have been identified to receive critical upgrades as part of the South Australian Government's commitment to reduce the risk of fatal and serious injuries and increase road safety.

This page provides an overview of key rural road upgrades and activities across South Australia.

What's happening

The State Government has allocated $10 million over four years (2024-2027) to undertake regional road safety treatments including shoulder sealing, Audio Tactile Line Marking (ATLM), safety barriers and rural junction activated warning system signage.

The highways and roads to receive upgrades as part of this funding package are:

• Southern Ports Highway and Southend Access Road junction
• Spencer Highway (Wallaroo to Moonta)
• Flinders Highway (south of Wangary to the junction at Western Approach Road)
• Goolwa Road (Mount Compass to Goolwa)
• Gorge Road (Amber Gully to Corkscrew Road)

The junction at Southern Ports Highway and Southend Access Road will be upgraded to include a left turning lane at the cost of $400,000, which will improve safety and accessibility.

This $10 million investment forms part of the State Government’s $98 million road safety package – one of three being delivered under a combined $346.1 million investment in partnership with the Commonwealth Government – and the South Australian Road Safety Action Plan 2024-26.

• South Australia's Transport Strategy

  South Australia’s regional areas and regional road network are important to the State’s economic and social fabric. Many regions face challenges related to transport connectivity. The state's first Transport Strategy highlighted the importance of enhancing regional connectivity, through improving the quality of services and providing greater choice in how people travel.
